Objectives:To evaluate the effects of double-acting desensitized varnishes applied to bovine tooth enamel bleached with 40% hydrogen peroxide on enamel calcium and phosphorus content and color stability.
Materials and Methods:The coronal part of 10 newly extracted bovine teeth (approximately 10x12mm in size) was divided into 5 regions for mineral exchange measurements. Color change measurements of 50 newly extracted bovine teeth were divided into 5 groups. Group 1 unbleached (negative control group), Group 2 was bleached with 40%HP (positive control group), Groups 3,4 and 5 were treated MI varnish, Clinpro White and Profluoroid varnish after bleaching, respectively. Then, all groups were exposed to the tea solution and enamel color measurements were made using the CIE Lab method with spectrophotometer. Mineral change measurements were determined by EDS and morphological changes were observed using SEM. One-way ANOVA, Tukey HSD tests and Tamhane's tests were used for statistical analysis.
Results:The content of calcium and phosphorus in enamel were like No bleachingMI varnishClinpro WhiteProfluoroidBleaching. The most color stability after bleaching was determined in teeth which were applied MI varnish applied group ((P< .05). The color stability of Profluoroid and Clinpro White applied group were similar (P> .05). There was a statistically significant difference between the groups in terms of △L and △b averages (P< .05).
Conclusions:MI, Clinpro White and Profluoroid varnish used after bleaching were effective in preventing mineral loss from tooth enamel and reducing the susceptibility of tooth enamel to staining with tea.
